half-life-unreachable: Semi-dampening of an unreachable, in the range of 1 to 45
minutes. The default value is 15 minutes.
reuse: Threshold for disabling route suppression. When the penalty value is below
this threshold, the route will be reused. The range is 1 to 20000. The default value is
750.
suppress: Threshold for enabling route suppression. When the penalty value is above
the threshold, the route is suppressed. The range is 1 to 20000. The default value is
2000.
ceiling: Upper penalty threshold, that is, the penalty value stops increasing when it
reaches the upper threshold. The range is 1001 to 20000. The default value is 16000.
route-policy-name: Name of a route policy, in the range of 1 to 19 characters.
If no value is specified for the arguments, their default values will take effect. The
half-life-reachable, half-life-unreachable, reuse, suppress, and ceiling arguments are
independent of each other.. Therefore, if you specify a value for any of these
arguments, you must specify a value for all the others.
Description
